how to get rid of bat

[wildchild]

ok so here's a new one. girl came home from work Mon night. suddenly I here her yelling. get up and she says "there's a bat in the house". ok I get dressed and come downstairs to shoo it out. Keep in mind I wear contacts and am blind without them. I manage to get him out into the porch and possibly all the way outside.
dig around the porch can't find him.
Last night she wakes me up again. apparently he was still in the porch and is now back in the house and flying around the bedroom. ok back out of bed, dress and arm self with a towel. I managed to wing him but he goes downstairs. I can't see him and she is quivering in a corner and doesn't want to come look for him. finally she pokes head around the corner, "there he is!!!!!" top of a cupboard. I wing him with a canoe paddle but.......he makes it into the living room. 1 hour later I tape the doorway shut and go to bed.
I have no idea how I'm going to find that little creep in there. too much crap he can hide around. I'm going to have to empty the room piece by piece tonight with my contacts in.
So any one know any tricks to attract a bat to a trap of some sort. I don't feel the need to kill it if not necesary but dead or alive he's going out of my house.
